Integrated model for software component selection with simultaneous consideration of implementation and verification

摘要: One important objective of component-based software engineering is the minimization development cost products. Thus, costs component implementation and verification, which may involve substantial expenses while under development, should be reduced. In addition, for these processes not considered individually, but in an integrated manner, to further reduce cost. current paper, decision model proposed assist decision-makers selecting reuse scenarios components used simultaneously determining optimal number test cases verification. An cost, satisfying required system reliability requirements. The Lagrange relaxation decomposition (LRD) method with heuristics was developed solve problems. Based on LRD, nonlinear condensed into a 0-1 knapsack problem subproblem scenario selection integer determination tests. Combined multiplier-determined heuristic, algorithm can determine global optimum solution. Simulations varying sizes problems sensitivity analyses were conducted, results indicate that LRD more effective than previous methods solutions problem. Highlights? select cases. ?
